Number Corner Adoption Sites

Our site truly benefited from having an MLC curriculum specialist on-site for targeted and individualized support for our staff having an expert answer our questions, share resources, and experience.

Kindergarten teacher – Napa, CA

We enjoyed having you set such a wonderful tone for our group. Thank you for sharing your expertise, bringing laughter to the room, and cultivating confidence for teachers.

Math coordinator – Avon, IN

I thoroughly enjoyed this training! Not only did I gain a better understanding of the program, but I also created a plan for my new teacher training. I highly recommend this training for all math leaders using Bridges in Mathematics.

Dean of instruction – Houston, TX

Even though I had been using Bridges for over a year, I was not aware of the many resources available to me. I am excited to dive into them and now feel like I can fully support teachers with their needs.

School administrator – Napa, CA

I enjoyed connecting with other math coaches from other parts of the country and hearing about their schools. The readings were helpful because I could directly apply them to the work I have been doing.

Course attendee – fall 2015 session

What a fabulous workshop! I came away feeling so much more confident in the curriculum and ready to share what I learned with colleagues who will be new to Bridges this next year!

Lead teacher – Snohomish, WA

This workshop stretched the thinking of our team and deepened our understanding of the models and strategies taught in Bridges. We came away prepared to provide ongoing professional development for our current teachers, and train new hires for successfully teaching with Bridges curriculum.

Lead teacher – Snohomish, WA

I enjoyed and learned something from each presenter. I left feeling enthusiastic and excited as we head into our second year of using Bridges. It’s great to hear what people in other districts are doing and to learn from it.
